5G Network Security for IoT Implementation: A Systematic Literature Review

Abstract

Fifth generation (5G) wireless technologies satisfies the growing demand for the Internet of Things (IoT), however, IoT devices are vulnerable to security threats due to the simplicity of their hardware and communication protocols, which imply possible attacks and security challenges. In this work we propose to conduct a systematic review of literature that relates 5G technologies to the internet of things and approach the security that the 5G network for IoT must provide. The Torres – Carrion method is used, raising four research questions: a) information security services, b) types of attacks in 5G-IoT, c) security in the layers of the IoT network architecture, d) strategies for 5G-IoT network security. Semantic search criteria were applied, in the Scopus database, obtaining 23 articles from 18 journals, the main studies were collected, it is evident that the blockchain is an efficient security mechanism that merits further study, that the physical layer is the one that receives the most active and passive attacks, such as denial of service (DoS) that is studied by several authors, together with mechanisms, architectures, protocols and algorithms that provide the security services of a mobile network.
